SimpleDB put_attributes raises SignatureDoesNotMatch error when UTF-8 value is given

See original GitHub issue

I am successfully using boto3 to save data to SimpleDB however, if I try to store a string which contains UTF-8 characters, the bellow error is thrown.

A quick hack for @samoconnor’s hack above, so as to only affect requests headed towards the sdb endpoint:

from botocore import endpoint
def make_request(self, operation_model, request_dict):
    if self._endpoint_prefix == 'sdb':
        request_dict['headers']['Content-Type'] = 'application/x-www-form-urlencoded; charset=utf-8'
    return self._send_request(request_dict, operation_model)
endpoint.Endpoint.make_request = make_request

Believe it or not there are a few SDB users out there still; it would be nice to get this fixed.
